Introduction
Reusable period underwear offers a sustainable, cost-effective, and comfortable alternative to disposable menstrual products. While many companies sell ready-made options, making your own DIY period underwear at home is accessible for those with basic sewing skills and the right materials. Whether you want to customize fit, maximize absorbency, or reduce your environmental impact, this guide provides actionable steps, material recommendations, and troubleshooting tips for creating functional, washable menstrual underwear.
Why Make DIY Period Underwear?
Homemade period underwear can help you save money over time, reduce waste, and tailor fit and absorbency to your unique needs. For many, DIY options also provide peace of mind regarding fabric composition and construction, especially for those with sensitive skin. Making your own allows you to reuse old materials, experiment with different layers, and create a product that’s easy to wash and durable for multiple cycles [1] .
What Materials Do You Need?
To make effective period underwear, you’ll need a combination of absorbent, moisture-wicking, and waterproof fabrics. Most DIY tutorials recommend:
- Base underwear: Start with a pair of comfortable, well-fitting cotton underwear (preferably full-coverage styles for best results).
- Absorbent layer: Cotton terry cloth, bamboo fleece, or Zorb fabric work well for soaking up moisture [2] .
- Wicking layer: Athletic wicking jersey or soft cotton to move moisture away from the skin [3] .
- Waterproof barrier: PUL (polyurethane laminate), a scrap of raincoat, or similar waterproof fabric to prevent leaks [3] .
- Thread and sewing supplies: Scissors, pins, needle, and sewing machine (if available).
- Paper and pencil: For tracing and creating a custom gusset pattern.
Step-by-Step Instructions
1. Draw and Cut the Pattern
Start by laying your base underwear flat and tracing the shape of the crotch area onto a piece of paper. This template will serve as your pattern for the absorbent and waterproof layers. For extra coverage, you can extend the pattern an inch or two toward the front or back, depending on where you need more protection [1] . Cut out your pattern and check that it fits neatly inside the underwear’s gusset area.
2. Prepare and Cut Fabric Layers
Using your paper pattern, cut out the following fabric pieces:
- One or two pieces of absorbent fabric (cotton terry, bamboo fleece, or Zorb)
- One piece of waterproof fabric (PUL or raincoat fabric)
- One piece of wicking fabric (athletic jersey or soft cotton, for the top layer)
If you have a heavy flow, consider cutting and layering two or more absorbent pieces for extra protection [3] .
3. Assemble the Absorbent Pad
Layer the fabrics as follows:
- Wicking layer (against your skin)
- Absorbent layer(s)
- Waterproof barrier (outermost)
Pin the layers together and sew around the edges using a zigzag or straight stitch, ensuring the pad holds together securely. Make sure your stitches catch all layers and the waterproof fabric is on the bottom side (facing the outside of the underwear).
4. Attach the Pad to the Underwear
Place the assembled pad in the gusset area of your underwear. You can attach the pad in one of two ways:
- Sew-in method: Securely stitch the pad to the inside of the underwear, ensuring the seams are flat and comfortable. This approach is most durable but is permanent.
- Removable method: If you prefer to be able to remove the absorbent pad for washing, you can sew snaps or Velcro to the pad and underwear. This option provides flexibility but may be less leak-proof.
For best results, sew around the entire edge of the pad, keeping stitches close to the edge to minimize bulk. Double-check that the pad is centered and fully enclosed within the elastic borders of the underwear [1] .
5. Finishing Touches
Once the pad is attached, reinforce any seams that feel weak and trim excess threads. Test the underwear for comfort and fit by wearing them for a short time at home before using them for a full day. If needed, adjust the pattern or add extra absorbent layers for heavier flow days [3] .
Alternative Approaches and Customization
There are several ways to customize your DIY period underwear for style and function:
- Different underwear styles: Full-coverage briefs provide the most space for absorbent layers, but you can adapt the method for boyshorts or bikini styles.
- Patterned fabrics: Use colorful fabrics for the outer layer to make your underwear look and feel special.
- Adjustable absorbency: By sewing in a pocket or snap system, you can add or remove inserts as needed for different flow days.
Some sewists use commercial sewing patterns specifically designed for period underwear, like the Jalie Patterns Sarah 4344, which provides printable templates and instructions for multiple sizes [2] . Choosing a pattern can make the process easier, especially for beginners.
Care and Maintenance
To maximize the lifespan of your DIY period underwear, rinse them in cold water after use, then machine wash with gentle detergent. Avoid fabric softeners and bleach, as these can affect absorbency and the waterproof barrier. Air-dry for best results, as high heat may degrade the waterproof layer over time [1] .
Potential Challenges and Solutions
Ensuring Leak-Proof Protection: The most common issue is leaks, usually caused by insufficient absorbency or gaps in the waterproof barrier. To address this, add extra absorbent layers, reinforce seams, and test with water before use.
Seam Comfort: Bulky or scratchy seams can be uncomfortable. Use flat stitches and trim excess fabric to prevent chafing.

Fit and Sizing: If the pad bunches or shifts, adjust your pattern or use a slightly larger base underwear for more stability.
Accessing Additional Resources
If you’re new to sewing or want step-by-step visual guidance, consider searching for video tutorials on reputable platforms like YouTube or sewing blogs. For example, the Jalie Patterns YouTube channel offers a complete sew-along for period underwear construction [2] . For written guides, blogs like Ellie & Mac and Mme L’Ovary provide detailed photo and text instructions [1] [3] .
If you’re not comfortable making your own, you can purchase eco-friendly period underwear from established brands after researching reviews and product materials.
